A Community-based Participatory Research (CBPR) Intervention for Childhood Asthma Using Air Filters and Air Conditioners
NCT00839046 · View on ClinicalTrials.gov ↗
Study Summary
The burden of childhood asthma is borne disproportionately by children living in poverty and in urban centers, many of whom are from communities of color and are at greater risk for environmental exposures. Given the complex interaction of physical and social environmental factors on childhood asthma, there have been increasing calls for comprehensive efforts using a community-based participatory research (CBPR) approach. Community Action Against Asthma is a long standing CBPR partnership in Detroit, Michigan, composed of representatives from community-based organizations, health and human service agencies, and academia. All members of the partnership have been actively involved in the development of the CBPR project proposed here. The specific aims are: 1) to test the efficacy of air filters (AFs) separately and when combined with air conditioners (ACs) to reduce exposure to particulate matter (PM), over and above a standard community health worker home visit (standard) intervention; 2) to test the association between any reduction in PM exposure through the use of AFs separately and when combined with ACs over and above a standard intervention and health outcomes in children with asthma; 3) to elucidate the causal pathways by which any intervention-related improvements in children's asthma-related health status is occurring. One hundred and fifty households in Detroit, Michigan with at least one child with mild persistent or moderate to severe persistent asthma will be enrolled to participate in the study. Households will be randomly assigned to one of three groups: a standard household intervention (or control) group; an AF only intervention group; or an AF+AC intervention group. Extensive health and exposure measures will be undertaken during the course of the 12 -month intervention. Given the role of PM in children's asthma-related health and the higher concentrations of PM in microenvironments, there is a need to test the efficacy and efficiency of novel appro

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00839046
The ClinicalTrials.gov registry entry for NCT00839046 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 126 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Michigan, which has 1,126 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Childhood Asthma appearing as the primary indexed condition, and to 3 interventions — of which Community Health Worker Intervention is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00839046 reports 1 study location spanning 1 distinct geographic area — top geographies include Michigan. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
